Title: Testing method for semiconductor device
Inventor: FUJII YASUHIKO
IPC: H01L21/66
Filed: 1990-05-23
Abstract: PURPOSE:To measure the lifetime of metal wiring with higher accuracy and greater efficiency by measuring electric resistance at a specified measurement cycle repeatedly until the rate of change in the electric resistance of a metal wiring formed on a semi conductor from its initial value exceeds a specified rate of change in threshold and then measuring the aforesaid rate of change at a shorter cycle than the aforesaid measurement cycle. CONSTITUTION:A constant current device 3 and a voltmeter 3 are connected with both ends of a metal wiring 1. A control device 4 which comprises a microcomputer outputs electric current value data to be applied to the wiring 1, inputs voltage data generated, records the voltage at a specified interval, and displays the data. A constant electric current is applied to the wiring 1 and the voltage is measured at a constant interval. Then, the rate of change (R/R0) from the initial resistance value R0 is com pared with a specified rate of change (k.t) in threshold which increases in a linear proportion with time elapsed t. The measurement, arithmetic operation, and comparison are repeated until (R/R0) exceeds (k.t). When the rate of change meets the aforesaid condition, the measurement interval is reduced. If the wiring 1 is broken or a predeter mined rate of change is attained, the time elapsed up to that point of time is displayed as the lifetime of the metal wire 1 and recorded accordingly.

Abstract: PURPOSE:To obtain high-quality tetrabromobisphenol A, directly usable as a flame retardant for resins in applications of electrical and electronic materials such as laminated boards and sealing madia without requiring special purification steps, reduced in hydrolyzable bromine content and improved in hue. CONSTITUTION:Bisphenol A(BPA) is brominated with bromine in an alcohol (preferably methanol) to produce tetrabromobisphenol A(TBA) useful as a flame retardant for epoxy resins, ABS resins, etc. In the process, the reaction temperature is regulated to -10 to +20 deg.C, preferubly 0 to +15 deg.C and water in an amount of normally 2-15wt.%, preferably 3-10wt.% based on the reaction solvent is added in an aging step. Thereby, the objective high-quality TBA with the hydrolytic bromine content reduced to 2-50ppm and improved hue is obtained. Furthermore, the aging time can remarkably be shortened by the aforementioned method as compared with that of conventional methods in which an alcohol is solely used as the reaction solvent. In addition, reaction of hydrogen bromide formed by the brominating reaction with the alcohol which is the solvent can also be suppressed.

Abstract: PURPOSE:To form a magnetic recording head of which the thin magnetic film contacts always stably with a recording medium and which can maintain stably a recording density characteristic by providing a main magnetic pole made into the construction in which the thin magnetic film is sandwiched by holding materials softer than the hardness of said film and an auxiliary magnetic pole in a manner as to face each other with the recording medium in-between. CONSTITUTION:The magnetic recording head is constituted with the auxiliary magnetic pole 2 having a winding 1 and the main magnetic pole 6 with the medium 5 having an FeNi layer 3 and a CoCr layer 4 in-between. The medium 5 travels while the pole 6 and said medium 5 are held in contact with each other under specified load in order to execute magnetic recording and reproducing at high density. The pole 6 consists of the thin magnetic film 7 and the non-magnetic holding materials 8 for holding said film. The materials 8 are made of the material softer than the film 7. The top end of the pole 6 itself wears down gradully in such constitution but the materials 8 wear down earlier than the film 7 and therefore the film 7 is eventually exposed at all times from the top end of pole 6. The stable recording density characteristic is thus maintained.
